Have you heard of pelvic clock exercises? According to an expert who spoke to The Oprah Magazine, these exercises are so important, and yet many women have never heard of them!

Experts say they can improve circulation to the pelvic organs (hello improved libido!); decrease tightness and stiffness for gals who sit at a desk all day; increase pelvic flexibility (always a good thing); improve balance and give you greater spinal stability. All good!

Here's the how to, from O:

Warm-up: Lie on your back to be sure that the back side of the pelvis has a full range of movement. Bend your knees and keep your feet flat on the floor. Keep your spine in a neutral position. Imagine that there is a clock on your lower abdomen, where 12 o'clock is at the bellybutton, 6 o'clock is at the top of the pubic bone and your hip bones are at 9 and 3.

The exercise: Bring the bellybutton down to the spine. This will make the "clock" tilt, down at the 12 position (bellybutton) and up at the 6 (pubic bone). Move your hip and pubic bones to rotate your clock to the side so that 3 o'clock hip is lower. Move around the clock, tilting the pelvis until the 6 o'clock position is lowest. Continue around the clock, hitting every number, until the 12 position is again the lowest position. Repeat two or three times, then reverse to repeat the cycle in the opposite direction, two or three times.

The routine: For healthy women without symptoms of pelvic floor impairment, the clocks should be done once per day to keep the pelvic girdle in shape. Those experiencing movement restrictions can try these two times per day (a.m. and p.m.).
